This should say enough. If you are a DIY it means that you should be ready to accept the consequences, including bad work, or the fact your
time is only worth $3.00 per hour. I understand the frustration of homeowners or contractors when people don't show up or do what they
are supposed to do. Also, there is a severe shortage of qualified plasterers, but still it is worth the wait for quality.

Other reasons for excessive cracking:

Finish coat cracking:
Too much lime in the finish coat, mortar too rich in the finish,
sand too fine.
    Most cracks only occur in the finish coat. These superficial cracks
may not be a danger of water infiltration, they can be avoided.

Lack of bond:

This is a source of larger deeper cracks, and loose areas.
Frequent causes:
Finish coat doesn't bond when resurfacing.
Brown coat too slick.
Bonding agent failure.
Inexperience.

Excessive cracking in the brown coat:

Sand in the brown coat too dirty or too fine.
Sand should be a yellow color and not too fine.
A red or brown color indicates too much red clay or dirt in the
sand.
